Most Frequently Asked Questions About Galvalume Roofs

So what exactly is Galvalume roofing?
 -- Galvalume is made up of 55% aluminum and 45% zinc alloy coated sheet steel.  

How is Galvalume made?
  -- Both Galvalume and galvanized sheet steels are made by a "continuous hot dip" process.  Coils of cold rolled steel are welded end-to-end and processed continuously on the coating line at speeds up to 600 feet per minute. The uncoiled sheet is first cleaned to remove rolling oils and mill dirt, and to reduce surface oxides so that the surface will accept the coating.  As it exits, the sheet proceeds through a pair of opposing air knives, which are positioned above the bath and equidistant from the surface of the sheet.  Most modern production lines have a coating thickness gauge feed-back control, which automatically adjusts knife air pressure and position to ensure that a uniform coating is applied.  Various finishing steps are carried out to complete the process, after which the sheet is wrapped around a reel into a coated steel coil.

Why is it good to use for roofing?
 -- Galvalume sheet is an ideal material for roofing because of its extraordinary outdoor corrosion resistance and resulting long life.  It can be readily rollformed into a variety of panels, as well as formed and stamped into tile and shingle facsimiles.   It can be used in modern day steel roof designs which are strong, yet light weight.  Galvalume sheet roofs won't crack and peel when subjected to the sun and weather, unlike conventional nonmetallic roofing.

What is the reflectivity of Galvalume roofing?
 -- Galvalume has good heat and sunlight reflectivity.  Its bright, white reflective surface makes it an ideal material for roofing.  During the summer it makes buildings cooler by efficiently reflecting away sunlight and reducing the amount of heat transmitted into the building.  Likewise, it makes buildings warmer in the winter by reflecting inside heat from the underside of the roof back into the building.  This good thermal reflectivity translates into energy savings by reducing cooling costs in the summer and heating costs in the winter.  Tests have shown that only half as much heat from solar radiation is transmitted into a building fitted with Galvalume roofing.

What are the advantages to purchasing Galvalume roofing over a built-up roof?
 -- Leaking conventional, flat non metallic roofs are the biggest problem on nonresidential buildings for architects and building owners.  Conventional roofs made with organic materials deteriorate even under normal environmental conditions.  Then, as a result of temperature fluctuations, they develop cracks, splits and tears.  Finally, because they are flat, ponding water inevitably penetrates these brittle, cracked systems and leaks into the building, causing damage to goods and disrupting activities inside the structure.  Leaks can be patched early in the life of the roof, but as time passes, leaks can become more frequent.  With that being said, Galvalume standing seam roofs (SSR) offer a weathertight, maintenance-free roof system that will last for decades on commercial, office and factory buildings.  They are economical to install, leak proof, maintenance-free, energy efficient, noncombustible and long-lived.

Can a Galvalume SSR be installed over an old flat built-up roof?
 -- Its light weight makes it suitable for retrofit applications over any old, leaking, conventional, nonmetallic roof system.  By installing the roof directly over the existing nonmetallic roof, costly and time-consuming tear-offs are eliminated, and activities inside the building can continue without interuption.

Top 10 Reasons to Install Metal Shingles

Courtesy Metal Roofing Magazine 

10.  Increases home value - A 2006 Metal Roofing Alliance article reports the appraised value of a home will increase by $1.35 per square foot when a metal roof is installed. 

9.  Reduces homeowner's insurance - Metal shingle roofs have a Class A fire rating, which can translate into a reduction on your homeowner's insurance rates. 

8.  Energy savings - Metal shingle roofing can save homeowners as much as 25 percent or more on heating and cooling costs and up to 40 percent in summer cooling energy costs.

7.  Environmental friendly - Going Green with metal shingle roofing is easy as it can contain up to 60 percent recycled material and is 100 percent recyclable at the end of its life.

6.  Tax incentives - Depending where your house is you may be eligible for certain federal, state and local tax credits.  Please check for benefits and rebates in your area.

5.  Add curb appeal - Metal shingles provide the beauty of a brand new shingled roof for years to come.  It's like having that new car smell two years later!

4.  Life expectancy - As a homeowner, you can expect a metal roof to last at least 2 to 3 times longer than an alternative.  Depending on the pitch and climate the average life span of an asphalt roof is 12 to 20 years.  Some metal roofs offer a 35 to 50 year warranty.

3.  Solar capability - Modern metal shingle metal roofing systems can be easily integrated with solar panels.  And, depending on where you live you may be eligible for state specific grants, local rebates or Solar Renewable Energy Credit benefits.

2.  Re-roofing made easy - While we often recommend against it depending on the age and condition of your home metal single roofing can be installed over your existing roof.  Not only does this eliminate the aforementioned landfill waste, you will save on installation time and installation costs.

1.  Little to no upkeep - It may sound like I am beating a dead horse here but there should be little to no upkeep with a newly installed shingle metal roof.  Unlike an asphalt roof, which can suffer from algae and moss growth, metal roofing does not.
